BACKGROUND

1. Field

The present disclosure relates to a device and method for enhanced aircirculation, and particularly for portable electronic devices.

2. Introduction

Over time, mobile devices such as wireless communication and computingdevices, are achieving higher data communications rates and computingspeeds. This higher performance generally comes with higher power drainwhich drives a need for greater energy storage capability in mobiledevice. Since the higher performance enables greater utility in mobiledevice, there is a desire for longer operational life between rechargingof an energy storage device in a mobile device which further drives theneed for greater energy storage capability. Further, since higher powerdrain causes a corresponding higher amount of heat generation in amobile device there is a need for improved thermal dissipation. Theenergy storage and conversion technology in existing mobile devicesrelates to electrochemical cell technology. For example, lithium ionbatteries are the energy storage and conversion devices used in mostmobile telephones. Alternative technologies, such as fuel celltechnologies, may provide greater energy storage capability but haveproblems including heat generation due to energy exothermic rechargingand conversion inefficiency; restricted operating temperature range; aneed to consume oxygen from ambient air; and condensation of generatedwater vapor.

Thus, there is a need for a method and device for providing enhanced aircirculation for portable electronic devices, including ones that utilizeenergy storage devices, such as fuel cells. There is also a need forautomatically and dynamically managing, for example, temperature, oxygenand/or moisture of a mobile device, to maintain the energy storage andconversion devices within desired specifications and tolerances. Thiscan help to prolong the useful life of the energy storage module and itscomponents.

In a preferredembodiment the thermal module is an energy storage device such as a fueltank. In a second preferred embodiment the thermal module is anelectronic computing module such as controller 220, audio circuitry 230,display 240, transceiver 250, user interface 260, memory 270, andsubscriber module 285. In a third preferred embodiment the thermalmodule is a housing 210. Other devices in the wireless communicationdevice 200 which are not shown in FIG. 2 may also be thermal modules.The thermal module is any device in wireless communication device 200with a restricted operating temperature range or which generates heatwhich may affect the temperature of another module which operates with arestricted operating temperature range.

In one embodiment, the module 290 includes a sensor 292 and processormodule 294, which are coupled to the controller 220. In more detail, themodule 290 can reside within the controller 220, can reside within thememory 270, can be autonomous modules, can be software, can be hardware,or can be in any other format useful for a module on a wirelesscommunication device 200.

The display 240 can be a liquid crystal display (LCD), a light emittingdiode (LED) display, a plasma display, or any other means for displayinginformation. The transceiver 250 may include a transmitter and/or areceiver. The audio input and output circuitry 230 can include amicrophone, a speaker, a transducer, or any other audio input and outputcircuitry.

Thememory 270 may include a random access memory, a read only memory, anoptical memory or any other memory that can be coupled to a wirelesscommunication device.

In more detail, the wireless communication device 200 shown in FIG. 2,can include: a housing 210; a controller 220 coupled to the housing 210,the controller 220 configured to control the operations of the wirelesscommunication device, and to provide ancillary computing operationswhich may be unrelated to wireless communications such as audio or videoprocessing, application processing, etc; memory 270 coupled to thecontroller 220; memory 270 coupled to the controller 220; a transceiver250 coupled to the controller 220; and a circulation module 290configured to detect a first threshold of an energy conversion device209 comprising at least one of a temperature threshold, oxygenthreshold, voltage threshold and moisture threshold, sense a temperaturein proximity to a thermal module comprising at least one of an energystorage device 207, and electronic computing module and a housing 210,and generate an air stream based on the detected first threshold and thesensed temperature. The air stream may be generated by, for example, anelectro-mechanical generator device such as a rotary motor driven fan, alinear motor driven piston, and air pump, a piezoelectric device, or thelike. Importantly, for thermal control of the mobile device the airstream generation is reversible. Reversibility of the airflow may beachieved by, for example, by selecting or switching an airflow path orvent, changing vent control timing, reversing the polarity of anelectrical input of an electromechanical generator, or a combination ofthese, or other methods.

In one form, the wireless communication device is configured with anenergy storage module 205. The wireless communication device caninclude: a housing 210; a controller 220 coupled to the housing, thecontroller 220 configured to control the operations of the wirelesscommunication device; a transceiver 250 coupled to the controller 220;and a circulation module 290 configured to detect a first threshold ofan energy conversion device 209 comprising at least one of a temperaturethreshold, oxygen threshold, voltage threshold and moisture threshold,sense a temperature in proximity to a thermal module comprising at leastone of an energy storage device 207, an electronic computing modulewhich can comprise any device or module which generates heat or has arestricted temperature range, and a housing 210, and generate an airstream based on the detected first threshold and the sensed temperature.

In a preferred embodiment the energy storage module 205 comprises anenergy conversion device 209 which is a fuel cell, and an energy storagedevice 207 which is a fuel tank. The fuel cell 209 can convert fuel fromthe fuel tank 207, into electrical energy. The electrical energysupplies and is dissipated as heat in electronic computing devicesincluding controller 220, audio circuitry 230, display 240, transceiver250, user interface 260, memory 270 and subscriber module 285. Thedissipated heat affects the temperature of each device or module in thewireless communications device 200. The energy storage device 207 may beanother source of heat. Significant heat can be generated duringrefueling, in the case of the energy storage device 207 containing metalhydride for adsorption of hydrogen fuel. Conversely, during operationthe release of hydrogen is endothermic, resulting in lowering oftemperature.

In the present state of the art, the housing 210 and the energyconversion device 209 have the most restricted operating temperaturerange. Since the housing 210 comes into contact with a user, itstemperature threshold is determined by the safety and comfort of theuser, such as about 45° C. For the energy conversion device 209,operation above an upper temperature threshold such as about 45° C. orbelow a lower temperature threshold such as about 0C may cause theenergy conversion device 209 to operate at reduced output voltage,current or power. The performance impact may also be permanent, albeitto a lesser extent. With a more temperature tolerant energy conversiondevice, a computation device may be more temperature-restricted, mostnotably the controller 220, the display 240 and the memory 270.

Operation of the energy conversion device may also be restricted by theavailability of oxygen. If the air supply is blocked or restricted theenergy conversion device 209 may operate at reduced performance, such aswith a reduced output voltage, current or power. The oxygen level may bedetected by use of an oxygen sensor, or indirectly by detecting theoutput voltage, current or power.

Operation of the energy conversion device may also be restricted by theavailability of water. Fuel cells employing a Polymer ElectrolyteMembrane (PEM) for example require a minimum amount of hydration foroperation, while too much water may reduce performance by, for example,blocking the flow of air to an electrode. Water vapor is also present asa byproduct of fuel cell operation. Operation of the energy conversiondevice 209 and other devices may be restricted by accumulation ofcondensed water vapor from the energy conversion device 209. Themoisture level may be detected by use of a sensor, or indirectly bydetecting reduced performance such as a lower output voltage, current orpower of the fuel cell 209.

Advantageously, the circulation module 290 can automatically anddynamically manage, for example, temperature, oxygen and/or moisture ofan energy conversion device 209, to maintain the energy conversiondevice 209 within desired specifications and tolerances. This can helpto prolong the useful life of the energy storage module 205.

A block diagram of a wireless communication method 300, is shown in FIG.3. In its simplest form, it can include: detecting 310 a first thresholdof an energy conversion module comprising at least one of a temperaturethreshold, oxygen threshold, voltage output threshold, a current outputthreshold, a power output threshold, and moisture threshold; sensing 320a temperature in proximity to a thermal module comprising at least oneof an external housing, a fuel tank and an electronic computing module;and generating 330 an air stream based on the detected first threshold310 and the sensed temperature 320.

In a first example, the method 300 is used to reduce the maximumtemperature of the energy conversion device 209. The process begins atstep 310. If at step 310 an energy conversion device threshold isdetected, then the process proceeds to step 320. Examples of thresholdsare temperature thresholds, voltage thresholds, moisture thresholds, andoxygen thresholds. If at step 320 a high temperature is sensed at theenergy storage device 207, which may occur if the energy storage devicehas recently been refueled, then the process proceeds to step 330. Atstep 330 an air flow is generated, and the direction of the airflow iscontrolled such that heat from the energy storage device 207 is carriedaway from the energy conversion device 209. If at step 320 a lowtemperature is sensed at the energy storage device 207, which may occurif the energy storage device has recently been endothermiclydischarging, then at step 330 the air flow direction is controlled suchthat heat from the energy storage device 207 is carried toward theenergy conversion device 209. Thus the direction of the air flow iscontrolled to reduce the maximum temperature of the energy conversiondevice 209.

In a second example, the method 300 is used to increase the minimumtemperature of the energy conversion device 209. Process step 310 is thesame as in the first example. If at step 320 a high temperature issensed at the energy storage device 207, then the process proceeds tostep 330. At step 330 an air flow is generated, and the direction of theairflow is controlled such that heat from the energy storage device 207is carried toward the energy conversion device 209. If at step 320 a lowtemperature is sensed at the energy storage device 207, then at step 330the air flow direction is controlled such that heat from the energystorage device 207 is carried away from the energy conversion device209. Thus the direction of the air flow is controlled to increase theminimum temperature of the energy conversion device 209.

The above first example provides a strategy to reduce the maximumtemperature of a restricted temperature device, and the second exampleprovides a strategy to increase the minimum temperature of a restrictedtemperature device. A third example serves to describe a method to bothreduce the maximum and increase the minimum temperature of the limitedtemperature range device, depending on conditions. Steps 310 and 320proceed according to the first and second examples. At step 330, if thesensed temperature of the energy storage device 207 is above the maximumoperating temperature of the energy conversion device 209 then theairflow is controlled to reduce the maximum temperature of the energyconversion device 209, according to the first example. If the sensedtemperature of the energy storage device 207 is below the minimumoperating temperature of the energy conversion device 209 then theairflow is controlled to increase the minimum temperature of the energyconversion device 209, according to the second example.

The method 300 can automatically and dynamically manage, for example,temperature, oxygen and/or moisture of an energy storage module, tomaintain the energy storage module within desired specifications andtolerances. This can help to prolong the useful life of the energystorage module and its components and help to maintain a maximumrecharging capacity.

In the earlier examples the temperature of the energy conversion device209 is regulated. Alternatively the method can be employed to regulatethe temperature of any device within certain desired specifications andtolerances. For example, display 240 may have a greater minimumtemperature range than the energy conversion device 209, and the airflowgeneration at step 330 may be controlled to increase the minimumtemperature of the display 240. The airflow may also be controlledaccording to a temperature sensed in proximity to the display 240 orother temperature restricted device.

In a preferred embodiment, the generating step 330 includes: controllinga direction of the air stream based on at least the sensed temperature;and activating the air stream based on the at least detected firstthreshold. While in the aforementioned examples at step 320 the sensedtemperature is a temperature in close proximity to the fuel storagedevice 207, there can be applications where the temperature is sensed inproximity to other heat generating or heat sinking devices, such ascontroller 220 and housing 210, or in proximity to the temperaturerestricted device such as energy conversion device 209 or display 240.Step 320 may include the sensing of multiple temperatures, and step 330may include generating an air flow based on multiple sensedtemperatures.

In one arrangement, the detection step 310 includes at least one of: (i)detecting a temperature limit above an upper threshold; and detecting atemperature limit below a lower threshold; (ii) detecting a oxygen limitabove an upper threshold; and detecting an oxygen limit below a lowerthreshold; (iii) detecting a moisture limit above an upper threshold;and detecting a moisture limit below a lower threshold; and (iv)detecting a voltage, current or power limit.

In connection with item i above, a temperature is detected correspondingto sensing a temperature in close proximity to the energy storage module205 or the energy conversion device 209 which is above an upperthreshold or below a lower threshold. The upper and lower thresholdsbeing related to the operating temperature range of the energy storagemodule 205 or the energy conversion device 209. Operation within therange ensures short and long term performance of the device. For exampleoperating at a temperature above the operating temperature range maycause reduced output voltage of the energy storage module 205, orreduced current or power generating capability, and increased air flowis needed for heat to be carried away from the energy storage module 205or the energy conversion device 209.

In connection with item ii, an oxygen level is detected. In a fuel cell,low oxygen level causes reduction reduced output voltage of the energystorage module 205, or reduced current or power generating capability.Increased air flow may be needed for the oxygen level to be increased.

In connection with item iii, a moisture level is detected. Fuel cellsneed to be hydrated for efficient energy conversion, and lack ofmoisture may cause reduced output voltage of the energy storage module205, or reduced current or power generating capability. Fuel cellsgenerate water vapor as a by-product, and condensed water vapor maycause flooding of a fuel cell, which would deprive the fuel cell ofoxygen and cause reduced output voltage of the energy storage module205, or reduced current or power generating capability. Increased airflow allows water vapor to be carried away from the energy storagemodule 205 or the energy conversion device 209. In this way flooding ofthe fuel cell electrode is minimized or avoided, although moisture maybe detected and controlled for other reasons, wherever condensation mayoccur such as at housing 210.

In connection with item iv, an energy storage module output is detected.The output is typically a measured voltage. As mentioned in items i, ii,and iii, the voltage may be reduced when the temperature, oxygen levelor moisture level goes above an upper limit, or below a lower limit. Itmay also be that the voltage is not reduced under high load impedanceconditions, but the voltage is reduced under high load impedanceconditions, which is a reduction in output current or output power. Itmay be advantageous, for reasons of size or cost of the mobile device,to simply measure the output voltage, current, or power instead ofsensing oxygen or moisture.

In a preferred embodiment, the wireless communication method 300 canfurther include at least one of: providing sufficient amount of oxygento the energy conversion module for energy conversion thereby ensuringadequate energy conversion reagents; providing a sufficient amount ofmoisture to the energy conversion module for energy conversion therebyensuring sufficient hydration without excess condensation for efficientenergy conversion; and providing a desired operating temperature rangeto the energy conversion device for energy conversion.

The energy conversion module can include at least one of: a battery, afuel cell and an electrochemical capacitor.
